Before you touch a single wire, it’s important to gather all the necessary tools and materials. Having everything ready will save you time and prevent frustration mid-installation.
Here’s a checklist of what you’ll need:
- Nest Hello video doorbell kit – This includes the doorbell, mounting plate, screwdriver, wire labels, chime connector, and installation guide.
- Smartphone or tablet – You’ll need this to download the Google Home or Nest app (depending on your model) and complete the setup.
- Wi-Fi network – Your doorbell requires a 2.4 GHz or 5 GHz Wi-Fi connection. Make sure your network is stable and covers your front door area.
- Screwdriver (Phillips head) – Most doorbell installations use standard Phillips screws.
- Voltage tester (optional but recommended) – This helps confirm that power is off and checks if your transformer meets Nest’s requirements.
- Drill and drill bits (if needed) – For mounting on brick, stucco, or other hard surfaces.
- Pencil or marker – For marking drill holes.
- Level – To ensure your doorbell is mounted straight.
- Ladder – If your doorbell is mounted high, use a stable ladder for safety.
Having these items on hand will make the process much smoother. Now, let’s make sure your home is ready for the Nest Hello.
Step 1: Check Compatibility
Not every home is automatically compatible with the Nest Hello. Before you start disassembling your old doorbell, take a few minutes to verify that your wiring and electrical system can support the device.
Check Your Existing Doorbell Wiring
The Nest Hello is designed to work with homes that have existing low-voltage doorbell wiring. If you currently have a wired doorbell, you’re likely in good shape. However, if you only have a wireless doorbell or no doorbell at all, you may need to run new wires—which is a more advanced project.
To check your wiring:
- Remove the front cover of your current doorbell (if it has one).
- Look for two thin wires connected to the back of the button.
- If you see wires, note their color and how they’re connected.
If there are no wires, the Nest Hello may not be the right choice unless you’re willing to install wiring. Alternatively, consider a battery-powered doorbell like the Nest Doorbell (battery).
Verify Transformer Voltage
The Nest Hello requires a transformer that outputs between 16 and 24 volts AC. Most older homes have transformers in this range, but it’s worth confirming.
To check your transformer:
- Locate your doorbell transformer. It’s usually found in the basement, attic, garage, or near your electrical panel.
- Look for a small metal box with wires leading to your doorbell and chime.
- Check the label for voltage output. It should say something like “16V AC” or “24V AC.”
If your transformer is below 16V, the Nest Hello may not get enough power to function properly. In that case, you’ll need to upgrade your transformer—a job best left to a licensed electrician.
Test Your Wi-Fi Signal
Since the Nest Hello relies on Wi-Fi for video streaming and alerts, a strong signal at your front door is essential.
To test your Wi-Fi:
- Stand at your front door with your smartphone.
- Check the signal strength in your Wi-Fi settings.
- If the signal is weak (one or two bars), consider installing a Wi-Fi extender or mesh network to boost coverage.
A strong connection ensures smooth video playback and reliable notifications.
Step 2: Turn Off the Power
Safety first! Before you touch any wires, you must turn off the power to your doorbell circuit.
Locate the Circuit Breaker
Your doorbell is connected to a low-voltage circuit, but it’s still powered by your home’s electrical system. To avoid shocks or short circuits:
- Go to your main electrical panel (breaker box).
- Look for a breaker labeled “doorbell,” “chime,” or something similar.
- If you can’t find a labeled breaker, turn off the main power switch temporarily.
Test the Power
Even after turning off the breaker, it’s wise to double-check that the power is off.
Use a non-contact voltage tester:
- Touch the tester to the doorbell wires at the button.
- If the tester doesn’t beep or light up, the power is off.
- If it does, turn off additional breakers until the tester reads zero.
Never assume the power is off—always test!
Step 3: Remove Your Old Doorbell
Now that the power is off, you can safely remove your existing doorbell.
Unscrew the Old Button
Most doorbells are held in place by two screws. Use your Phillips screwdriver to remove them.
Once the screws are out:
- Gently pull the doorbell button away from the wall.
- You’ll see two wires connected to the back.
Disconnect the Wires
Carefully disconnect the wires from the old doorbell. They’re usually held in place by small screws or push-in connectors.
Tip: Use the wire labels included in the Nest Hello kit to mark which wire goes where. This will help during reinstallation.
If the wires are short or frayed, you can trim them slightly and strip about 1/4 inch of insulation to expose fresh copper.
Remove the Old Mounting Plate (if applicable)
Some doorbells come with a mounting plate. If yours does, unscrew it from the wall. You’ll replace it with the Nest Hello’s mounting plate.
Set the old doorbell and plate aside—you won’t need them anymore.
Step 4: Install the Chime Connector (If Needed)
This step is crucial if your home has a mechanical (non-digital) doorbell chime. The chime connector prevents voltage spikes that could damage your Nest Hello or cause it to reboot unexpectedly.
Determine Your Chime Type
Open your indoor chime box (usually located near the front door). Look inside:
- If you see mechanical parts like solenoids or hammers, you have a mechanical chime.
- If it’s a digital display or silent module, you likely have an electronic chime and may not need the connector.
When in doubt, install the chime connector—it won’t hurt.
Install the Chime Connector
The chime connector is a small device that connects to your chime’s terminals.
Follow these steps:
- Turn off power at the breaker (again, for safety).
- Open the chime cover.
- Locate the two terminals where the doorbell wires connect.
- Disconnect the wires from the chime.
- Connect the wires to the chime connector’s input terminals.
- Use the included wire nuts to connect the chime connector’s output wires to the chime terminals.
- Secure the connector inside the chime box with tape or a zip tie.
- Close the chime cover.
This step ensures your Nest Hello gets steady power without overloading the chime.
Step 5: Mount the Nest Hello
Now it’s time to install the Nest Hello itself.
Attach the Mounting Plate
The Nest Hello comes with a mounting plate that screws into the wall.
- Hold the plate against the wall where you want to install the doorbell.
- Use a level to make sure it’s straight.
- Mark the screw holes with a pencil.
- Drill pilot holes if needed (especially for brick or stucco).
- Secure the plate with the provided screws.
Connect the Wires
Take the two wires from your wall and connect them to the back of the Nest Hello mounting plate.
- Loosen the terminal screws on the plate.
- Insert one wire into each terminal.
- Tighten the screws to secure the wires.
- Make sure the wires are snug but not over-tightened.
The Nest Hello is polarity-insensitive, so you don’t need to worry about which wire goes where.
Attach the Doorbell
Now, snap the Nest Hello onto the mounting plate.
- Align the doorbell with the plate.
- Gently press it into place until it clicks.
- Use the included security screw to secure the doorbell and prevent theft.
Step 6: Turn the Power Back On
Once everything is connected, it’s time to restore power.
- Go back to your breaker box.
- Turn the doorbell circuit back on.
- Wait a few seconds for the Nest Hello to power up.
You should see a light ring on the front of the doorbell. It will flash yellow at first, then turn solid white when it’s ready to connect.
Step 7: Set Up the Nest Hello in the App
The final step is configuring your doorbell using the Google Home or Nest app (depending on your model).
Download the App
If you haven’t already:
- Download the Google Home app (for newer Nest Hello models) or the Nest app (for older versions) from the App Store or Google Play.

Complete the Setup
Once connected, the app will guide you through:
- Setting up motion zones (areas where you want alerts).
- Enabling familiar face detection (if available in your region).
- Choosing notification preferences.
- Testing the doorbell chime.
You can also adjust video quality, night vision, and audio settings.
Step 8: Test and Optimize
Before you call it a day, test your new doorbell to make sure everything works.
Test the Video and Audio
